Could you let me know the URL of the page that you're on, when it doesn't work.
On this page:
http://www.wildaboutbritain.co.uk/node/add/flexinode-1
I've tried the link in the first sentence "To add a map to your location, please
click here to create one..." and it works, so I guess you must be clicking somewhere else - an old page maybe
